CRESTING.

SPECIFICATION forming part of Letters Patent No. 633,622, dated September 26, 1899.

Application filed December 21,1898. Serial No. 699,899. No modeLl To (1/77 71:71.07, it nmq concern.-

Be it known that I, ALBERT G. SOUTHER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Crestings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in cresting, especially that formed of sheet metal, providing the finish for the ridge of houses, &c.

The object of my invention is to improve the construction of such cresting, stiffen the upper edge of the cresting proper, and provide an improved cap and cresting combined.

To this end my improvements have reference to two separate thicknesses forming, substantially, two side halves of the cresting and secured at their upper edges, have reference to a bent'over portion of the upper edge of one half adapted to clamp the upper edge of the other half of said cresting, have reference to a special combination of cap and cresting and to other points of details herein after described and claimed.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure 1 represents a perspective side and end view of a special capping and eresting embodying my improvements; Fig. 2, an end view of the same; Fig. 3, an enlarged view of an interlocking tubular edge, and Fig. 4a perspective view of a cresting having a closelyfolded upper edge securing the two halves.

It has been common in the trade to provide a capping for a ridge composed of sheet metal in place of the ordinary ridge-pole strips. One form of such capping consists of a roll forming something more than one-half of a cylinder and provided with flanges for each slope of the roof.

I present herewith a capping combined with a cresting and in substantially two side halves A A, the lower part of each side forming the flange B and the upper portion of each side forming the cresting proper, as shown in Fig. 2. The upper edges are secured together, preferably by means of a bent-over portion of the top edge of one side embracing the top edge of the other side. Fig. 2 shows this -1 and 4.

l bent-over portion constituting simply a tube with a slit, in which is inserted the upper edge of A. Fig. 3 shows the tubular joint having the upper edges of the two sides formed with interlocking reverse bends a a. The slot-opening of the side A admits the bent-down edge of the side A, and the hollow ridge is centrally mounted, so as to show a half round on each side of the cresting. Fig. 4 shows the upper edge bent over to form a closed fold upon the upper edge of the matching side. It will be seen by the drawings that the upper edge of one side is extended above the upper edge of the other, so as to allow of forming the bent over portion or hollow stiffening-ridge. Thus the upper edges are parallel with each other, but one side is a little longer than the other in order to form the tubular ridge. A tube open along the side is thus formed on the overlapping extended edge of one side by being benthorizontallyand then turned over, so that when complete it presents substantially half the tube on each side of the two plates forming the cresting proper, as shown in Figs. 2 and 3. The end of the eX- tended side edge when in its completed position thus forms a radial inward bend substantially vertical, with which the downwardturned edge of the other side interlocks, as in Fig. 3. The object of this engagementof the upper edges is to provide stiffness along the length of the crest and allow of constructing the cresting in two side pieces substantiallyin halves, but the top of one side being somewhat extended to allow of forming the bentover clamping engagement with the other side. Thisstiifening-ridgeatthe joiningedge of the cresting proper may extend along the entire length of the cresting, as indicated in Fig. l, where it connects the divided portions of the cresting proper, oritmay form agreater or lesser portion of the top edge of the cresting, according to the character of the design of the cresting proper, as-indicated in Figs.

In either case the function of combining the two sides and stiffening the eX treme top edges of the divided cresting proper is apparent. Furthermore, the construction of the cresting is facilitated by providing two separate pieces forming the sides, and which when combined as above specified constitute a complete oresting adapted for mounting on the ridge or elsewhere, as required. If nec' essary, a number of rivets O are inserted near the base of the cresting proper to secure the roll-cap D from springing open and to facilitate the manufacture.

\Vhile I have shown and described the combined cresting and cap with the roll-cap formin the base portion, I do not limit myself to this form of base for the cresting proper, but may form the lower portion of each side in any suitable designsuch as in Fig. 4, for instance.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An improved cresting consisting of a roll-cap combined with a cresting proper, formed of two thicknesses substantially in side halves, each half constituting one-half of the cresting proper and of the roll-cap in the upper and the lower portions respectively, and means to secure said side halves together.

2. An improved cresting consisting of two side halves, each half forming a portionof the cresting proper and of the capping, and a stiffening-clamp integral with one side provided at the upper edges of the cresting proper, substantially as described.

An improved cresting consisting of two side pieces forming substantially halves of the cresting, and constituting the cap and the cresting complete when opposed and joined, the one having its upper edge extended beyond the matching half and bent over to clamp the opposite side, substantially as described.

4. The combination with two sheets of metal having edges parallel and one sheet overlapping the other, of a hollow stiiTening-ri-dge formed on said parallel edges, consisting of a tube open along the side and formed centrally on the overlapping sheet and with a radial inward bend, and a reverse matching bend formed on the other sheet to slip into the tube and interlock, substantially as shown and described.

In testimony whereof I affiX my signature in'presence of two witnesses.

ALBERT G. SOUTHER.
